You gotta give yourself more credit.👍

One more thing that proves you and your wife are good people. As you said in the video, bees do alot of stuff for food production, other insects etc. Bees are important for the world and I thank you.

Hi Josh & it's is Randy and i like yours video is cool & Thanks Josh & Friends Randy

That was a high stress moment... averted.. Better to set up the press-shrink fit in the press with the press ready to press before heating the part while the stud is cooling off in dry ice. If the stud is even a tiny bit off axis even with a few thousands of clearance the stud will likely get stuck on the way down the hole. More often than not, the press I needed to avert a Oooops and not fun at ll re-do.. There is a tendency for metal to stick when they are close together, this is why clearance alone is not enough. Some means of mechanical aid (force) is often needed to over come this tendency for separate metal parts to wanna cling together.

Good stuff

When you milled the square portion, how did you reference the square faces to the round rotary spindle portion? Is it just relying on the setup of the square on the 4 jaw on the lathe?

Congratulations on 100k. Good job on the part too.

Makes me wince every time you put your finger on a moving part in the lathe. I worked with a guy that used to do that. Emphasis on 'used to'.

Please get a tripod for your camera

Nice job. Lucky that 3/8 pilot didn’t snap looking at the hole. Makes you wonder if there was some slag rolled into the plate looking at where the oxy cut went 🤷‍♂️

Just run across your channel. Great content.Great repair!

so stupid, wast a lot of times and material to turning it .

I'm always amazed at how much replacement parts cost. I did some work for a shop that made replacement parts for diesel engines and the owner said "if you had to build a new engine with all genuine replacement parts you could pay off the national debt." I appreciate you sharing the prices of OEM parts and it shows how important what you do is to the small business man (aka farmer).

I watched my dad and neighbor working machines in a small shop through the window, he wouldn't let me in the shop. I've seen my dad get so stressed he would go outside kick the trash can and smoke a cigarette. Then went back to work! He didn't want me to be a machinist! Years later he pushed me to be a auto mechanic!

Happy days Josh, turned out lovely, hope you didn't feel too pressed 😂 cheers buddy, a shot well earned

Being able to make your own dry ice is nifty. Thanks for the video.

Typical Josh topper "get it right those time" always.

I'm glad I'm not the only one who always goes the wrong way first with coaxial indicator.

Big thing about using dry ice vs LN2 is -109 degree F vs -320 degree F, you only get about one-third of the shrink; gotta keep that in mind. With LN2, the part probably would have dropped right in (at the expense of 2 hours driving to get the stuff). Anyway, nice job there, it's always interesting to see how people approach a problem and get it done.

I don't even like watching those press fits and I'm not even responsible for the outcome. Assuming it's one of those things that no matter how many you do, you're never really relaxed. Is there a formula or table you machinists use to know how how to size those? Or just learned from experience and hopefully as little trial and error as possible? I'd imagine the properties of the materials matter too for how much they expend and contract.

What did you buy it for ? I got it and the hoe

I’m pretty sure that CNH actually stands for Can Not Have. Owned by parent company Fiat, which must be Italian for Fix It Again Tomorrow. I have been operating and maintaining a first generation New Holland large square baler for 25 years this year. It is appalling how many parts are no longer available (NLA in CNH speak). If they are available the price is obscene. FWIW -- CIH labeled pre New Holland/Case IH merger large square balers were built by Heston here in the US. After the merger, CIH large squares were rebadged New Holland machines. All large square balers built by New Holland except the New Holland 2000 were built in Zedelgem Belgium.

I have never done it that way and mabye that is because that has more wear than I have seen. I use a boring head (left hand boring bar faceing the inside of boring head) and machine it to a smaller diameter and make a sleeve to bring it back to spec.

Thank you Josh!

Nice to have that press nearby!

Awesome crane. Love it. You are amazing, your skill set is so vast and varied! A X7 railroad crane operator!!!

congrats on the 100k, been here since like 5k if i remember correctly, thanks for the content, love the cool stuff like shrink fits and whatnot, cheers buddy

Just a note about sawing off the pin with a slitting saw, slitting saws are pricey but my favorite alternative nowadays is the 8 inch carbide tip blades they sell for metal cutting skilsaw type saws. They are cheap like 40 bucks and less kerf, I have one on an R8 arbor I use all the time for cutting down pieces too short to hold in the bandsaw, slotting, or even have used it in the angle head for cutting plate clamped down to the table. Works great and in 4 years now I am still on the first saw blade of the 2 pack I bought!

As long as the beer dose not open till you are done. Once the beer comes out the wrenches stay put away in my shop.( unless it's my own shit.)

Yeah screw those people that just complain I don't see them doing precise machine work with repeat customers

Beautiful Job Josh.

Thanks for taking the time to post this, I always enjoy "repairs" ! Cheers

Hey Josh, not a machinist but enjoy and respect your work!

a beer never worked for me maybe a 12 pack

I think if you had cleaned both the bore and mating shaft with some fine grit or emory, it would have been a cleaner fit and no press would have been needed. What looks like a smooth finish to our imperfect eyes is really very rough under a scope. Keep up the great work Josh.

That new ENCO lathe is sweet!

Good one Josh . Plan B is always the press , preferably close by ! I like that boring head , although it is completely different to the D'Andrea i used to use . That had 3 speed feed & rapid return traverse . Cheers 👍

'Do it right the first time'. Trying, and will get there, eventually!?.

hi very important to do when you're pressing there is a book that gives you the exact diameters for a press fit slip fit based on diameter of the shaft. you can find one the Internet Next time you press shaft give yourself a small taper about taper so you know it's going in straight and put a heavy grease on the shaft and the bore.

Try liquid nitrogen next time

Do ever wash your pants?

Real good fix

Never did say what the parent metal was. It looked like steel to me and not cast Iron. The pin you turned was Steel but what grade? Inquiring minds need to know. Loved the video and the use of coaxial indicator. You logged the center position of the pin hole and then macked off the pin. I loved the results. .003 fit is tight. I noticed you did not skim the surface of the wheel the saw must have left a satisfactory finish. Hope the baler runs another fifty years. New Holland balers and swathers are around sitting out in fields rusting. My guess is pin was 1045. But I have been wrong before. Cheers.

That was a brown pants moment at the end. Glad it worked out.

Saving perfectly serviceable machinery one part at a time. Try that with CNC. Writing the program alone would probably exceed what you charged. Want one or two parts use 'old time' shop machinery. Want a thousand parts use CNC.

Hope you enjoyed the beer, you sure deserve it.

i was drinking a beer while watching the video

I even needed a beer after that pin stuck! glad the press was handy and it worked!
